Constructed from Kynar (PVDF) with a black finish, this fitting accepts 1\/4 inch OD tubing on both sides and forms a secure, tool-free connection rated to 250 psi. The FKM o-ring provides compatibility with a wide range of fluid media, including aggressive chemicals. It also carries a vacuum rating of 28 in-Hg, making it suitable for both pressure and vacuum service. Plumbers, HVAC technicians, and industrial service techs use this fitting where tubing must pass through a panel wall with a leak-free seal on each side.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial applications where corrosion resistance and chemical compatibility are required. Typical installations include refrigeration drain lines, chemical feed systems, pool and spa equipment plumbing, and instrumentation tubing routed through enclosures or panels. The Kynar body holds up to harsh fluid exposure, and the push-to-connect mechanism allows for quick field installation without soldering, threading, or compression tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design for tool-free tube insertion and release\u003c\/li\u003e\n  \u003cli\u003eKynar (PVDF) body for superior chemical and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eFKM o-ring compatible with a broad range of aggressive media\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi pressure and 28 in-Hg vacuum\u003c\/li\u003e\n  \u003cli\u003eBulkhead-style body mounts through panels with connections on both sides\u003c\/li\u003e\n  \u003cli\u003eBlack color for easy visual identification in multi-line installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement push-to-connect bulkhead union for systems using 1\/4 inch OD tubing where Kynar material and FKM o-rings are specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified plumber, HVAC technician, or instrumentation technician. Shut off fluid supply and relieve system pressure before removing or installing any fitting. Ensure the panel cutout diameter matches the fitting body before seating the bulkhead nut. Confirm tubing OD and cut tubing square with a clean, burr-free end before inserting into the push-to-connect port to ensure a proper seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Kynar (PVDF)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: FKM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Rating\u003c\/strong\u003e: 28 in-Hg\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4 inches L x 4.5 inches W x 4.25 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FB4BU4-HBLK\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543584178482,"sku":"FB4BU4-HBLK","price":22.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/29d32dd9cb324e1c61128d29bec71410_49660f08-9bbe-4645-a6b4-aac0fa3ff33a.jpg?v=1785920696","url":"https:\/\/voomisupply.com\/products\/parker-fb4bu4-hblk-bulkhead-union-fitting-1-4-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
